The e-cigarette mainly consists of three parts: a tobacco pipe containing a nicotine solution, an evaporation device, and a battery. When used, the nicotine solution evaporates when heated and is sucked into the mouth. Since nicotine is usually dissolved in propylene glycol solution, smokers can exhale white mist when they smoke electronic cigarettes to achieve “spray cloud”. According to personal preference, smokers can add flavors such as chocolate and mint to the tobacco pipe.

For this reason, the safety of additives in e-cigarettes is worrying. The German Federal Center for Health Education pointed out that nearly 90% of the gases that people inhale from electronic cigarettes are propylene glycol. This chemical can stimulate the respiratory tract within a short period of time. It is unclear what kind of adverse effects the long-term and repeated inhalation of propylene glycol will have on the human body. In addition, in addition to commonly known ethanol, glycerol, and fragrances, US researchers have also detected carcinogenic nitrosamines in some e-cigarettes.

In addition, the principle of electronic cigarettes is through heated liquid nicotine. The key word in this sentence is nicotine. Nicotine is harmful to your body, no matter how you use it. According to researchers, nicotine contracts blood vessels and increases blood pressure, but it also puts pressure on the heart. Therefore, electronic cigarettes are inherently harmful to health because they can cause heart attacks and strokes.
